Just got a call from the dealer again....this was now the 5'th time i had to bring my car there in the last two months. Luckily they're giving me a loaner car and only charging me for the parts this time. The last time i was there they replaced the crankshaft sensor, and this time they said the camshaft sensor needed replacing. They said in hindsight they should have replaced both last time.
Anyway, that'* water under the bridge. The reason i'm posting here is because i was told that the dealer thinks the main bearing is going bad. I had noticed a "rattle" noise myself in the past, but the dealer thinks it'* is the main bearing, not anything to do with the coupler in the nosecone (which i had already contemplated replacing with a ZZP one). They said the "rattle" is louder once the engine gets hot, and the other main noticable thing is a bit of "jumping" in the boost gauge at idle. The dealer thinks that might be blowby, due to a bad main bearing in the back of the charger.
I know i repeated myself a bit in there, but i wanted to get it all out.
SO, oh experienced supercharger guru'*, what do you suggest? The dealer says they wouldn't want to do anything because you can't change the bearings in the rear and it'* $1300 for a new supercharger. Can i get one cheaper, or change bearings myself....or is there any way of knowing if the rattle is the coupler vs. bearings?
Thanks in advance. love this forum
